Nepenthes tobaica Sumatra, Borneo

Highland Nepenthes are pitcher plants that live in tropical mountains characterized by warm days but a sharp drop in temperature at night. The ideal temperatures are between 24-26 degrees during the day and 12-14 degrees at night.
They really love the evening humidity, which brings relief from the strong daytime sun.
Some species are more tolerant of summer temperatures, but extremely hot days over 28 degrees or nights that are too cold, below 8 degrees, should be avoided.
Intermediate Nepenthes, on the other hand, are more tolerant regarding daytime heat but do not withstand frosts or temperatures that are too cold in the evening.
The ideal temperature for intermediate ones is between 28-30 degrees during the day and 14-16 degrees at night.
